CASPER, Wyo. (AP) - Wyoming has a lot of older wells that are past their prime and a lot of old fields. The Salt Creek field north of Casper, for example, was first tapped over 100 years ago but still holds crude that couldn't be collected by conventional means. The Enhanced Oil Recovery Institute announced recently that about $2.2 million of research is going into boosting production in vertical stripper wells.

BILLINGS, Mont. (AP) - Federal officials shut down an experiment on diseased wildlife from Yellowstone National Park after inspectors questioned protocols for handling infected bison. The U.S. Department of Agriculture program examined whether administering birth control to bison would reduce transmissions of the brucellosis. Brucellosis causes animals to prematurely abort their young. Inspectors raised questions about keeping infected and non-infected bison in the same pen, prompting an end to the program last year.

RIVERTON, Wyo. (AP) - Attorneys for the state of Wyoming say the Eastern Shoshone and Northern Arapaho tribes have not raised any new issues in a boundary dispute with the state that would merit a U.S. Supreme Court review. The tribes want the Supreme Court to hear arguments in a dispute over the Wind River Indian Reservation boundaries.

GILLETTE, Wyo. (AP) - A 46-year-old Wyoming man has pleaded guilty to second-degree murder in the death of his wife last year at their Gillette home. Timothy Welch's guilty plea last week was part of an agreement in which prosecutors and his attorney recommend he spend 30 to 50 years in prison. The judge doesn't have to abide by the agreement when he sentences Welch on Aug. 14.
